POWER SAVER to reduce electric bill at home, do you have one?

That's good. Those bulbs are LED(Light Emitting Diode) type. This is the trend after the CFL(Compact Fluorescent Lamp). It is efficient even if it has very low watts rating.

@Marilynda1225 Great idea Marlyn. In all projects we do, the requirement and recommendation we give is LED because it is efficient and cut cost on the consumption of electricity although in my country LED lamps are more expensive.

I've invested in those LED bulbs too

@moneychaser Oh, I see. So, that's how it should be. I should have that in mind. Or maybe my husband knows that too.

@SIMPLYD Right madam...:)

I doubt greatly those who are selling it, they are plainly sales people and they don't understand how their products work. Those products may be true, can lower electricity cost, but first, they need to determine which home or establishment can it be useful. Different homes and establishments have different types of electrical loads. They need to know the reactive power present by using a reactive power measuring tool, then determine which of their devices is applicable. In small houses, it might be negligible, they just get your money.

@topffer You are right friend. I think this is applicable to industrial and commercial establishments or in homes with heavy loads especially in motors, all inductive type loads.

@moneychaser I read that inductive loads represent 2% of the bill in a French home, and reactive energy is not billed to individuals (electric meters are not the same than for big consumers).

@topffer That is true. It is in here where the power saver comes in. In the electrical field, we call this power factor correction. In greater loads such that in a commercial or industrial establishment, this would apply and more effective because it has more reactive power in them compared to that 2% in our homes.

They do. But before connecting it to your home, we should first know the amount of reactive power of your homes if present. We just do not buy the device. It might not be effective, To my opinion, this is what the manufacturer lacks. They have the idea but it must be supported properly and correctly.

That's being wise, @Letranknight2015. I agree that this device may somehow lower electricity bill because house loads can be made of reactive power. It is the TRUE power which is effectively consumed while the INDUCTIVE power is not because it just raises the current passing to your kilowatt-hour meter, thus, raising your bill in effect. My question is, did this seller ever check the inductive current in those homes, to just sell one device a homeowner could afford? I'd been discussing this with my fellow electrical engineers and this is what they are missing. Sellers know only that Power Saver device but don't know how it works and where will it be effective.

@Letranknight2015 That's true. If you have heard about capacitor banks used in transmission lines, it has the same purpose with this device. Only, our homes have lesser inductive power compared to that of transmission lines. The purpose is to correct the power factor present in our homes, but the amount of reactive power present, how did these none-technical sales persons know it? They cannot even explain what is inside their product.

@moneychaser No ones even making a product demonstration on this thing so I didn't take the product seriously.
